Automated distributed analysis tests are necessary to ensure smooth operations of the ATLAS grid resources. In this work we present the recent developments of GangaRobot, the ATLAS HammerCloud functional testing system. GangaRobot is designed to perform regular tests of all grid sites by running arbitrary user applications with varied configurations at predefined time intervals. Success or failure rates of these test jobs are individually monitored. Test definitions and results are stored in a database and made available to users and site administrators through a web interface, the ATLAS Site Status Board (SSB) and the Service Availability Monitor (SAM). The test results provide on the one hand a fast way to identify systematic or temporary site problems, and on the other hand allow for an effective distribution of the workload on the available resources.
